Product Specification

GCK Low Voltage Switchgear

Product Details

Low Voltage Switchgear GCK Low-voltage Switchgear Panel, Withdrawable type

Application: mainly applicable in places with high automation and a need to communicate with computers, like large power stations and petrochemical systems, as a low-voltage distribution device for distribution and motor controlling, and reactive power compensation in the power system.
Protection degree: IP30, IP40. Bus type: three-phase four wires, three-phase five wires. Operation type: in-place, long-distance, and automatic

Operating conditions

1. Ambient air temperature: -5℃ ~+40℃.
Daily average temperature: ≤35℃.
When the actual temperature exceeds the range, it should be reduced by the
capacity accordingly.
2. Transport and store temperature: -25℃ ~+55℃. Do not exceed +70℃ in a short
time.
3. Altitude: ≤2000m.
4. Relative humidity : ≤50%, when temperature is +40℃ .
When the temperature is low, a larger relative humidity is allowed. When it is +20℃, the 
relative humidity can be 90%. Since the temperature change will cause our
condensation.
5. Installation inclination: ≤5%
6. Applicable in places without corrosive and flammable gases.
Note: Customized products are available.

Feature

GCK panel is a combination structure with a bolt. The complete panel is composed of door, terminal board, baffle plate, supporting frame and drawer, busbar, etc.
Basic frame adopts the FA28 type or the KB type (Ctype) to combine with. Total structural components of the frame are connected by a self-tapping screw.
It should add to the door, face plate, baffle plate, supporting frame, and drawer to complete the panel according to the requirements.
The installation hole of the body and component modules is E=25mm, changeable, flexible, and convenient to install.
Drawer unit height is divided into ½ unit, 200mm, 300mm, 400mm, 500mm, and 600 mm series. The loop current decides the drawer he; the ht, virtual installation height is 1800mm.
GCK panel withdrawable function unit adopts a special push (pull) mechanism, light
structure, and perfect interchange. It indicates of working position, test position, and
isolating position mechanical locking condition. Install an additional padlock for the operating handle.
The frame and inner metal components are galvanized to ensure reliable earthing.
GCK basic frame is a combination assembly-type structure, adopting a standardized module design. For a combination assembly-type, the standard module design.
Compact structure, flexible assembly, can be assembled into a protection, measurement, and control, indicating, etc. standard unit. Can choose assembly according to requirement, to form different frame Features and drawer units.
1. The cabinet frame
C-type material adopted for the mainframe, Frame parts, and Special parts will be provided by our company to ensure accuracy and quality.
● Parts forming size, hole size, Equipment intervaadopts modularization. (E=25mm)
● The internal structure should be galvanized.
● The top cover is detachable, the horizontal bus can be installed easily after removing the top cover, Hand ring
● External phosphating treatment; Then use electrostatic epoxy powder coating.
● The cabinet frame is divided into the busbar compartment, the functional compartment, and the cable compartment into three separate intervals. This can prevent accidents diffusion and is convenient to charge and repair.
2. Functional unit (Withdrawable part)
● Functional unit: Feeder unit, Motor unit, utility power unit.
● The high modulus of the drawer unit is 200mm, including 1/2unit,1unit,2 unit,3 unit, four size series.
Unit loop rated current below 630A.
● Each MCC Cabinet can install 9 sets of drawers with 1 unit, or 18 sets of drawers with ½ unit.

3
● The compartment door plate is interlocked between the operating mechanism and drawer; the door can be opened until the main switch is in the closed position
● The main switch operating mechanism can be locked in a closed or open position by a padlock, and the equipment can be maintained safely.
● There is a main circuit outlet plug, an auxiliary circuit secondary plug, and an earthing plug at the back of the function unit.
● The earthing plug ensures the protection circuit continuity when the drawer is on. Separation tests the connection position.
● Functional unit compartment by metal partition board.
● Compartment valve, can be opened and closed automatically, with drawers pushed and pulled so that in the compartment without touching the vertical busbar.
3. Busbar system
● Vertical bus uses a polycarbonate engineering plastic sealed shell
● GCK, GCL busbar system uses 3P4W, 3P5W. Horizontal busbar will be installed at the top of the cabinet, N phase, PE phase. It can be installed on the top of the cabinet, and can also be arranged in the cabinet's bottom.
